Where exactly were you stuck? Like I wrote on the game's page "No need to rush... Observe, understand, choose a direction, and ALIGN! [...] every information you need for the puzzles are right there for you, just pay attention to the shapes, shadows and reflections"
I went upwards following the route of the small half diamonds. However, I wasn't sure were I needed to move towards; there was no glowing object (or something) showing were the exit was.
